I would just like to mention that my college buddies and I did this game in the van on the way to Florida. Obviously, since we were driving, we weren't drinking, but it was fun nevertheless. It wasn't strictly jazz musicians either, since I was the only guy who liked that music anyway.
But I have to say that I kicked everyone's ass at that game. Mainly by naming musicians they never heard of. They kept saying, "You're just making this shit up!" and then I'd give a short biography of the artist I just named.
